IMPROVEMENT IN SWAGING-RLLS.

The Schedule referred to in these Letters Parent and making Dart of thesame.

To all 'whoop 'it ma/y concern Be it known-that I, JOHN F. THOMAS, ofIlion,

' Herkimer county. in the State of New York, have in-y vented anImproved Machine for Rolling, Plating, and Swaging Metal; and I herebydeclare the following to be a full and exact description thereof,reference being had to the accompanying drawings, forming part of thisspecification.

The nature or essence of my invention consists in combining, with astationary anvil, having a curved face, a roller, arranged in a frame,pivoted upon the' --the pivots C, upon which the roller-frame Dvibrates.

The stand E supports, in suitable bearin gs, the shaft F, which has oneach end a crank, G, connected, by rods or bars H, pins e, and pivots11, to the rollerframe D.

The shaft F may be turned by a belt on the pulley I, 0r by gears, orotherwise, as may be preferred, and the roller J, having journals in theboxes N, will thus be traversed across the face of the anvil B, so as toact upon such material as may be placed upon said face. l

The turning ofthe roller, as it moves over the face, is secured by thegearK and toothed segment L, and its height above the face may beadaptedto the thick- .'iess of the material or article to be operated upon bythe set-screws M, in the top ofthe frame, the boxes N Ybeing arranged totraverse inthe frame, andthe teeth ofthe gear K and seginentLbeing madelong enough to allow the roller to be raised and lowered to a limitedextent, Without their being separated. A second face, O, may be arrangedoutside the roller- `frarne, witha' corresponding roller, P, on the endof the journal of the roller J, to traverse across it, and both therollers and the'facesy may` be provided with scores c, for the receptionof such dies and patterns as the work to be performed may require.

In the case of articles having a shank or tangat one side, as hoes, forexample, they may be rolled in one direction on the face O, andin thedirection across' or at right angles to that on thev face B, thebox N,at the opposite end of the roller J l. being supported by a wedge, orotherwise, when the roller I? is used to prevent that end of the rollerfrom being depressed by the upward strain upon the roller l?.

The cranks G and the connecting-rods Il have several holes d in each,for the crank-pin d, in order that the roller may be arranged totraverse over such a part of the face B, and to such an extent upon itas the work in hand may require.

The foregoing,`being a description of my improved machine for rolling',plating, and swaging metal- 1. I claim, the combination of the roller J,pinion K, and vibrating frame D, with the segment-rack L,

anvil B, and forming-dies c c, all constructed, arranged, and operatedsubstantially-as described.

2. The arrangement of all the parts of the improved machine, hereindescribed, as and for the purpose speciiied.
